How do Chinese (GB) and International naming conventions for solar cables differ?

In the international market, solar cables are defined by specific harmonized standards (like the European system) or North American UL classifications. The Chinese system uses the GB (Guobiao) standard, which utilizes Pinyin initials to denote the cable’s characteristics.

Chinese System (GB/T 33594): Common models are identified as WDZ-PV1-F (Low smoke halogen-free, flame retardant PV cable).

International System (EN/IEC): The gold standard is H1Z2Z2-K. The “H” denotes harmonized, “1Z2Z2” indicates specialized cross-linked LSZH insulation and jacket, and “K” signifies flexible stranded conductor.

North American System: Focuses on PV Wire or USE-2 (Underground Service Entrance) ratings as per UL 4703.
